WEATHER-STRIP.

Application filed September 27, 1917. Serial No. 193,522.

T 0 all whom it may concern:

Be it known that I, JosEPH P. GLASER, citizen of the United States, residing at 109 Third Ave, Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in weather strips and more particularly to the class of weather strips especially designed for casement windows and similar structures, in which cooperating metal strip elements are provided respectively upon the lower rail of the sash and the sill of the window frame.

The object of the invention is to provide a light cheap construction of the character referred to that will be strong and durable in use and will afford a very efficient seal and weather proof joint.

The invention will be understood from the following detail description when considered in connection with'the accompanying drawings forming part hereof and wherein is illustrated a preferred embodiment of the invention and one modification thereof.

In the drawings:

Figure 1 is a vertical section of a casement window having applied thereto a weather strip constructed in accordance with the present invention, the window sash being shown in closed position.

Fig. 2 is a detailed perspective view of the sill strip, and

Fig. 3 is a similar detail view illustrating a modified form of sill strip.

Referring to a detail description of the drawings, wherein like reference characters designate corresponding parts throughout the several views, the special embodiment of the invention illustrated in Figs. 1 and 2 of the drawings, comprises a metal strip element A constructed of flexible sheet metal, such as sheet zinc, copper or the like, and having spaced upstanding double wall flanges ab, an intermediate connecting portion a and outstanding flanges (Z2-03 at opposite sides, the upstanding flange a having its upper portion bent outwardly at substantially right angles, and the upstanding Specification of Letters Patent.

flange 6 having its upper portion 7) bent to extend at an upward inclinationx The metal strip A is secured upon the upper face of the sill of the window frame byany suitable means, shown in the present instance as rows of tacks passing throughtheintermediate connecting portion such as a, and the outstanding flange a Secured upon the lower face of the sash rail 0 within the rabbet-o for cooperation with the sill strip is a strip element D constructed of flexible sheet metal. This strip element has a rebent curved portion at one side providing a substantiallyhook shaped part d forming a pocket at one side of the strip, and the strip at its other sidehas a downwardly inclined sealing portion at, the inclination of said sealing portion d corresponding to the angle of inclination of the upwardly inclined portion 6 of the-flange?) of the sill strip. The sash rail E is provided with a second relatively small rabbet e at its lower outer marginal portion, and the strip D is positioned so that the downwardly inclined-sealing portion at thereof extends from the inner wall ofsaid rabbete.

When the window sash is in its closed position, as shown in Fig. 1 of the drawings, the upper outwardly bent portion atof the flange (1 extends within the hook part d of the sash strip D, the lower face of'the forward against the one face of the outer portion of the hook shaped part 03, and the upper inclined portion 5' of the flange b fitting tightly against the outer face of the downwardly inclined sealingportion 03 of the sash strip D, said upper inclined portion 7) being disposed beneath the upper wall of the rabbet e and at its, outer marginal edge making a tight fit with the upper and inner side Walls of the rabbet.

The upstanding flange a is shown pro- CHAMBERLIN' METAL part of said portion a fitting tightly K and L, the members being constructed of independent strips of flexible sheet metal.

The member K is provided with an upstanding flange is having its upper portion 72 bent outwardly, and Outstanding side flanges 70 this strip member being formed by doubling the strip upon itself intermediate its side marginal portions. The strip L has the double wall extending upstanding flange Z the upper portion Z of which is bent to extend at an upward inclination, and the strip has outstanding flanges Z Z*. The strip members KL are assembled in interfitting relation, as shown, with the outstanding flange is of the member K overlapping and fitting against the outstanding flange k of the, member K. The members K-L interfitting one with the other are secured together in adjusted position upon the upper face of the sill of the window frame by a row of tacks or other suitable fastening members m passing through the overlapping outstanding flanges k and Z of the respective members.

It will be observed that my improved weather strip provides a double barrier against the entrance of dust, moisture, air, etc., and the particular formation of the interfitting sealing portions of the sill strip and the cooperating strip and parts on the sash constitute a very eflicient weather proof fitting. The construction is of a strong, durable nature and can be economically manufactured from stock materials.

I desire it to be understood that minor changes and variations in the particular construction, illustrated in the drawings, as will appeal to those skilled in the art and within the scope of the appended claims may be made without departing from the spirit of the invention.

What I claim is:

1. The combination with a casement window including a swinging sash, and a window frame having a sill, of a weather strip comprising a metal strip element secured upon the lower face of the sash rail, said strip element having a substantially hook shaped part forming a pocket at one side marginal portion thereof and a. flat downwardly inclined sealing portion at its other side marginal portion; and a metal strip element secured upon the upper face of the sill of the window frame, said last mentioned strip element having a pair of up standing flanges separated from each other to form a channel therebetween, one of the flanges having its upper portion bent outwardly at an angle, the outwardly bent portion fitting within the pocket of the sash strip, and the other of said flanges being fiat and extending vertically, said last mentioned flange having a flat upper portion extending at an upward inclination corresponding to the angle of inclination of and fitting flat against the outer face of the downwardly inclined sealing portion of the sash strip over a substantial area transversely of the strips when the sash is in closed position.

2. The combination with a casement window including a swinging sash, and a window frame having a sill, the lower rail of the window sash being provided with a rabbet at its lower outer marginal portion, of a weather strip comprising a metal strip element secured upon the lower face of the sash rail, said strip element having a substantially hook shaped part forming a pocket at one side marginal portion thereof and a flat downwardly inclined sealing portion at its other side marginal portion extending from the inner wall of the rabbet in the sash; and a metal strip element secured upon the upper face of the sill of the window frame, said last mentioned strip element having a pair of upstanding flanges separated from each other and providing a channel therebetween, one of said flanges having its upper portion bent outwardly at an angle, the outwardly bent portion fitting within the pocket of the sash strip, and the other of said flanges having a flat upper portion ex tending at an upward inclination over and flat against the outer face of the downwardly inclined sealing portion of the sash strip with its upper marginal portion extending beneath the upper wall of the rabbet in the sash and fitting against the said upper wall at the inner edge thereof when the sash is in closed position, said straight upper inclined portion of one strip and the straight downwardly inclined portion of the other strip being of substantial width and fitting against each other over a substantial area transversely of the strips.

3. The combination with a casement window including a swinging sash, and a window frame having a sill, of a weather strip comprising a metal strip element secured upon the lower face of the sash rail, said strip element having a substantially hookshaped part forming a pocket at one side marginal portion thereof and a flat downwardly inclined sealing portion at its other side marginal portion; and a metal strip element secured upon the upper face of the sill of the window frame, the last mentioned strip element being constructed from a single strip of flexible sheet metal doubled upon itself intermediate its side edges at difl'erent points to provide a pair of upstanding double walled flanges spaced apart, with an intermediate horizontal connecting base portion, and horizontal base flanges at the sides of the upstanding flanges, one of said upstanding flanges having its upper portion bent outwardl at substantially right angles, said outwardly bent portion being adapted to fit within the pocket of the sash strip, and
